**How severe does this issue affect your experience of using Ray?**

- High: It blocks me to complete my task.

**Unable to ADD Worker nodes to a cluster of Raspberry Pis**  
Once Head node is set up (no issues here), here’s what i have already attempted to add Workers:

- With config yaml file
- Without config file i.e. adding manually
- Playing with ssh with password and without Password (i.e. keys)

Nothing I tried solves the problem. I am on the verge of breaking my keyboard #frustrating  
Please help
